The return value of this function is a dictionary of statistics, each of which is a non-negative integer. Core statistics: - ``"allocated_bytes.{all,large_pool,small_pool}.{current,peak,allocated,freed}"``: amount of allocated memory. - ``"reserved_bytes.{all,large_pool,small_pool}.{current,peak,allocated,freed}"``: amount of reserved memory. - ``"active_bytes.{all,large_pool,small_pool}.{current,peak,allocated,freed}"``: amount of active memory. - ``"requested_bytes.{all,large_pool,small_pool}.{current,peak,allocated,freed}"``: memory requested by client code, compare this with allocated_bytes to check if allocation rounding adds too much overhead. For these core statistics, values are broken down as follows. Pool type: - ``all``: combined statistics across all memory pools. - ``large_pool``: statistics for the large allocation pool (for size >= 1MB allocations). - ``small_pool``: statistics for the small allocation pool (for size < 1MB allocations). Metric type: - ``current``: current value of this metric. - ``peak``: maximum value of this metric. - ``allocated``: historical total increase in this metric. - ``freed``: historical total decrease in this metric. Args: device (torch.device or int or str, optional): selected device.
